Instructions

Step 1: Preheat oven to 350°F. In a large mixing bowl, whisk together 1/2 cup melted unsalted butter, 1 cup granulated sugar, and 1/2 cup packed brown sugar until well combined and smooth.
Step 2: Add 2 large eggs and 1 tsp vanilla extract to the butter-sugar mixture, whisking until fully incorporated.
Step 3: Sift together 3/4 cup all-purpose flour, 1/4 cup unsweetened cocoa powder, 1/2 tsp baking powder, and 1/4 tsp salt directly into the wet ingredients. Stir gently until just combined.
Step 4: Fold in 1/2 cup creamy peanut butter in dollops, swirling lightly through the batter for pockets of peanut flavor. Then, fold in 1 cup semisweet chocolate chips evenly.
Step 5: Pour the batter into a greased 8x8-inch baking pan, smoothing the top. Bake for 25-28 minutes until a toothpick inserted in the center comes out with moist crumbs. Cool completely before cutting into squares.
